Experimenting with DBAN and alike

[rubberducky]

Has anyone done an experiment wiping all sectors in a hard drive multiple times with random numbers using DBAN or alike and then send it to Data Recovery Company to see if they can recover anything? How much money would it cost to recover data in such circumstances?

No and you can't. One pass of zeros is enough to prevent the data from being recovered.

This would be interesting to do for anybody with about 1500$ to spend on research. If you try it, let us know the results.
Anyways, I agree with Steve, and I think we all know the results already.

That's good to know because I am not about to go through all of that. That is just far too much trouble. Sheese!

When I initially heard about Returnil, I assumed that if a person used it, they would not need to wipe their computer. But I guess that isn't so. I wonder how much stuff sticks to the hard drive while using Returnil? Any thoughts on that?

I did have a conversation with technical support at Kroll Ontrack (http://www.krollontrack.com/) several months ago, asking if their data recovery services can restore data that has been overwritten (and not simply deleted). The answer: “no.”

You may wish to contact other data recovery service providers, and ask the same question.
